Blender to AS3.0 exporter & modifier support: short how-toPosted by Dennis on Apr 6, 2009 in 3D, Blender • 5 comments
The latest Blender to ActionScript exporter supports modifiers. A detailed desciptions of what these are can be found here on the Blender site.
If you have absolutely no idea about what a modifier is then this post will give you a very short introduction
With modifiers you can make changes and additions to existing meshes. The specific modifier that we are going to use here is called the “Array Modifier”. According to the Blender documentation an Array Modifier “creates an array of copies of the base object, with each copy being offset from the previous one in a number of possible ways. “. Let’s open Blender and see for ourselves.
We will use the default cube without any changes. The modifier tab is located in the “Editing Buttons” window. To go to this window press F9:
The Modifiers tab can be found in the lower right corner of the buttons window. Clicking on the “Add Modifier” button will open a drop down menu that lists all modifier types. Pick “Array” from this list. The Modifier tab and the 3D view should look like this now:
The cube now has a duplicate that is put next to the original cube. The duplicate can’t be changed, only the original object is changeable.
The number of objects can be increased by entering a new value in the “Count” field. The space between the objects can be increased by changing the values underneath the “Relative Offset” button:
We can make this a bit more exciting by adding rotation. You can see that there is no explicit setting for this in the Modifiers panel. A special object called an “Empty” can be used for this purpose. To add an empty press the spacebar on the 3D view and choose “Add > Empty”. Press F7 to go to the Object buttons window and make sure the object is named “Empty”:
Now we need to tell the Array Modifier to use this object as the source object. Select the cube by right-clicking on it in the 3D view. Now press F9 to go back to the Editing buttons. In the Modifier panel click on the “Object Offset” button and enter “Empty” in the input box below this button:
Select the empty in the 3D view and press “r” to rotate. You can see that all objects rotate accordingly:
Now we’re all set to export our object. For more details about this check the exporter page. Take a look at this page to see the object live in action with Sandy 3.1. Download all the source files here.
